STUD FOR EYEGLASSES.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed June 8, 1905. Serial No. 264,264.

To (LU w/w'm 116 may concern:

. Be it known that I, CHARLES GooDwIN, a citizen of the United States, residing at East Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Studs for Eyeglasses, of which the following is a specification accompanied by drawings forming a part of the same, in which- Figure 1 represents a front view of an eyeglass containing my improved stud. Fig. 2 represents in extended form a sheet-metal blank from which the box portion of the stud is formed. Fig. 3 represents the blank with the laterally-projecting wing bent over upon the body portion of the blank. Fig. 4 represents the box portion of the stud formed by bending the body portion of the blank. Fig. 5 represents a sectional view of the box portion of the stud, the section being shown on line 5 5, Fig. 4. Fig. 6 represents a sectional view of the box portion of the stud on the .same plane as that shown in Fig. 5, but with a hole formed in the folded wing-piece to receive a screw for attaching the nose-guard and bow-spring. Fig. 7 represents a detached view of the stem by which the box portion of the stud isattached to the eyewire. Fig. 8 represents my improved stud with the stem and box portion soldered together, and Fig. 9 represents a completed stud shown in sectional view and representing the bow-spring and nose-guard inclosed in the box portion of the stud.

Similar reference-figures refer to similar parts in the different views.

My present invention relates to an improved method of constructing the studs in an eyeglass by which the bow-spring and nose-guard are attached to the eye-wires; and it consists in providing a wing-piece integral with the box portion of the stud and adapted to be compressed by the attachingscrew, by which the nose-guard and bowspring are held in place.

My improved stud, like those now in common use, comprises a box portion adapted to inclose the bow-spring and nose-guard and having a stem attached thereto, by which the box portion of the stud is connected with the eye-wire.

The box portion of the stud by my im proved method of construction is formed from a sheet-metal blank (represented in plan view in Fig. 2) consisting of a body portion 1, having a central hole 2, semicircular notches 3 3 in its opposite ends, and proj ecting from one side and integral therewith a wing-piece 4, which is bent over upon the body portion 1 upon the broken line 5, as represented in Fig. 3. The body portion of the blank is then bent at right angles upon the lines 6 6 and also upon the broken lines 7 7, bringing the notched ends together and forming a rectangular box, as shown at 8, Fig. 4, the semicircular notches 3 3 forming the circular hole 9 to receive the tenon 10 of the stem 11. The hole 2 in the top of the box portion is adapted to receive the head 12 of an attaching-screw 13, Fig. 9. A hole 14 is formed through the wing-piece 4, as shown in Fig. 6, of less diameter than the head of the attaching-screw. The tenon 10 of the stem is soldered in the hole 9, as shown in Fig. 8, and a screw-threaded hole 15 is formed in the stem 11 coincident with the holes 2 and 14 to receive the attaching-screw 13. The bowspring 16 and the nose-guard 17, each provided with holes to receive the attaching-screw 13, are then inserted in the box portion 8 of the stud and beneath the wingiece 4. The screw 13 is then inserted and the head 12 screwed down firmly against the upper surface of the wing-piece 4, causing the nose-guard and bow-spring to be firmly compressed between the bottom of the box 8 and the under side of the wing-piece 4. The wing-piece 4 increases the binding-surface and prevents the movement of the noseguard or bow-spring from being communicated to and loosening the attaching-screw 13, and the elasticity of the wing-piece tending to lift the screw from its socket exerts a strain upon the screw-threads and prevents the accidental loosening of the screw.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a stud for eyeglasses, the combination with a stem and a box portion attached thereto, of a'wing-piece integral with the box portion and bent within the box.

2. In an eyeglass-stud, comprising a box to receive the nose-guard and bow-spring and an attaching-screw, the combination with the box, of a wing-piece connected to the box and arranged to receive the pressure of the attaching-screw.

3. In an eyeglass-stud, the combination with a box adapted to receive the bow-spring and nose-guard, and having an opening to IIO receive the head of a screw, of a wing-piece said box and arranged to be compressed by attached at one edge to the box and having said screw.

a hole smaller than the. head of the screw. Dated this 1st day of June, 1905.

4. In an eyeglass-stud, the combination CHARLES GOODWIN. 5 with a box and a stem attached thereto, of a Witnesses:

screw passing through said box into said LoUIs LYoNs,

stem, and a yielding Wing-piece inclosed in ADE PRIGHARD.
